Metastatic visceral calcification identified by bone scanning

D Choy, I P Murray

    Skeletal Radiology
    |January 1, 1980
    PubMed
    Summary

    Radionuclide bone scans revealed widespread visceral calcification in a patient with metastatic breast cancer and hypercalcemia. Treatment led to significant resolution of this metastatic calcification, demonstrating the scan

    Area of Science:

    • Nuclear Medicine
    • Oncology
    • Radiology

    Background:

    • Metastatic breast carcinoma can present with hypercalcemia and visceral calcification.
    • Radionuclide bone scanning is utilized to detect bone metastases and assess calcification.

    Observation:

    • A patient with metastatic breast carcinoma exhibited abnormal 99mTc-pyrophosphate uptake in lungs, stomach, myocardium, kidneys, and thyroid, indicative of visceral calcification.
    • Scintigraphic abnormalities showed marked reduction after achieving normocalcemia and complete resolution 18 months later.

    Findings:

    • The patient's visceral calcification was more widespread than typically reported.
    • Bone scanning effectively identified extensive metastatic visceral calcification.
    • Therapeutic intervention led to near-complete resolution of scintigraphic abnormalities.

    Implications:

    • Bone scanning is a valuable tool for detecting visceral calcification in hypercalcemic patients, aiding in treatment response assessment.
    • Discrepancies between autopsy and scintigraphy findings for visceral calcification warrant further investigation into etiological factors.
    • This case highlights the potential for significant resolution of visceral calcification with appropriate management.
